So we know Richter can dual cast a spell by using both hands. Could a fourarmed race quadro-cast by using all four at the same time? What about an eight-armed race?
Maybe two dual castings at once? I imagine they'd have to be really powerful mentally to get through it with four hands going at once. Richter got by with a healthy dose of luck and Alma. I imagine a race like you describe would need some serious training befour hand.
I have wondered/asked about this myself awhile back. They would probably have an Inherent knack of learning standard Duel Casting of Spells that use only one hand in the Casting of them due to their natural mental process using four or more hands, anything more then that (Tri-Quad Casting) would likely be just as difficult as it would be for most standard Humanoids. They would also have the capability to learn to Cast Duel Two Handed Spells unlike Standard Humanoids. Mental Strain of Spell Casting would be a bigger issue then Mental issue of Hand Control/Manipulation. Other things I wondered about was wether Races with more Hands, Arms, Legs, Fingers, ect, could ware more Magical/Crafted Items & Equipment then a Standard Humanoid (more Rings, Bracelets, Armbands, Anklets, ect, (or Necklaces, Torcs, Headbands, ect, if they had more then one head like an Ettin?). Also what about Items designed for Tails (like those used by some Kobolds, Tail Weapons, Rings, Armour, ect) or for Wings? Could those with multiple Tails or Wings get th he benefit of more Magical Item Slots as well? Also what if Spells designed for &/or Created by Sentient Spell Casting Races with not only more Arms, Hands and Fingers then Humans but also those Spells created by Races with non-standard manipulator appendages like Tentacles, Paws, Wings, Trunks, Tails, Eye Stalks, (or multiple Mouths&Tongues for that matter), ect. Would a Standard Humanoid be even capable of Learning those Spells? And if they could would they be able to actually Cast them, I'd think probably not in most cases. The same might be tried to a lesser extent for Spells created by Races with really, really, really different mental processes even if they were Humanoid? Now with Richters Limitless Ability he might very well be able to at least Learn Spells created by those Races with radically different body designs then most Humanoids or designed to Cast with Non-Standard Appendages even if others couldn't, but still would have the issue of actually Casting them that most standard Humanoid Races would have, unless he was to also have a Polymorph Spell or Item that allowed him to take a Form Suitable for doing so? His Ability would most likely allow him to also learn any Spells from Races with truly Odd and Different Thought and Mental processes that others would find difficult to Learn, and he could probably Cast them as long as it was within his Physical capability to do so, although there maybe some Mental Side Effects from doing so? Also there are probably Spells out there Created by Races that while are created by Humanoids or still Cast-able by Humans(ect) would be forced most part pointless to Learn or to Cast, for instance a Spell that Allows the Caster to Breathe Air created by an Aquatic Water Breathing Race would be pointless for a Human Mage to Learn, as would a Spell that allows a Dark Sight Mage see in Normal Light, (but similar spells that can be cast in someone else would potentially be useful). Although some seemingly useless Spells created by other Races for themselves might still be potentially useful in the right situation, like a Spell from an Amphibious Race designed to allow its Caster to get more Skin Mucous to give it more protection from a dry environment might be used by a Human Mage to make him more Slipper?
When Richter was with Nexus...when he was going to choose his ascension... "Unless Richter was wrong, Nexus was using more than a dozen schools of magic at once to cast the spell he was weaving. The appearance of different lights at once showed that he wasn't only shifting between different schools, he was using multiple types simultaneously. Clearly Richter has a very long way to go with multiple casting. Also this shows that multiple arms are not necessary for multiple casting.
Yes, but I suspect that there's probably Talents that help with that, and quite likely he was able to do that largely because of the type of Higher Entity that he is and due to his Profession(?) as an Auditor, Although there are probably other ways of learning to do it.
In one of the Forgotten Realms books I read a Drow Wizard that was tied up was able to (after several Hours worth of attempts) Cast a Spell using his Toes/Feet to free himself, although he did say that after centuries of jokes at his expense for his Abnormally Long and Flexible Toe's (for a Drow) the joke was on them.
